摘要

Heat generator intended for burning solid fuels, comprising a cyclone hearth (1) fed by at least one first line (2) intended to introduce a mixture of primary air and the said fuel, tangentially in relation to the wall of the said hearth (1), the said hearth being additionally fed by a line (13) for introducing additional air, at least one exit (7) being provided for molten ash and at least one other exit (6) being provided for the combustion effluents. According to the invention the said hearth (1) comprises a vertical lengthwise axis, the said solid fuel is a waste or a fuel derived from a waste which has a high content of meltable ash which has a CaO/SiO2 ratio of between 0.2 and 1.2.
